Definitions
- This invention relates to a current limiting ultra-fast contact breaker which can be used at medium voltage and although more particularly suited to direct current electrical traction in rolling stock or in fixed equipment, can also be used in alternating current applications.
- cut-off devices in traction networks include ultra-fast mechanisms for opening the contacts and a blowing box in which the arc created is confined and cooled. These devices give rise to significant costs due to maintenance operations and the replacement of worn parts.
- An object of the present invention is to provide a semiconductor assisted ultra-fast contact breaker which does not have the disadvantages of the known devices in the state of the art such as described above.
- Another object of the present invention is to provide an ultra-fast contact breaker capable of cutting off a DC current with a similar efficiency in both directions.
- An additional object of the present invention is to provide a particularly high-performance contact breaker which is not very costly and does not give rise to high maintenance costs.
- the contact breaker includes an ultra-fast cut-off mechanism provided with a moving contact bridge and with fixed contacts, to the input and output terminals of which there is connected an assistance circuit.
- the assistance circuit includes at least two parallel branches, a first branch including two opposed diodes in series, each directed in the non-conducting direction for the current entering the circuit, a second branch including two opposed thyristors, each directed in the conducting direction for the current entering the circuit, and an LC oscillating circuit which connects the common point of the two diodes and the common point of the two thyristors, the thyristors being remote controlled or controlled via a current sensor which is built in and which detects the exceeding of a previously fixed triggering threshold which can be adjusted in the control electronics.
- FIG. 1 is the basic diagram of the assistance circuit according to the present invention.
- FIG. 2 illustrates the functioning of the said contact breaker
- FIGS. 3 and 4 show particularly advantageous variant embodiments of the assistance circuit according to the present invention.
- FIG. 5 shows a variance of FIG. 3 in which thyristors are replaced by diodes and other thyristors.
- the input terminals 1 and the output terminals 3 of the contact breaker 5 including a fast cut-off mechanism represented only by the moving contact bridge 7,7' and by the fixed contacts 9, 9', and an assistance circuit 10 connected in parallel with the terminals 1 and 3.
- the assistance circuit 10 includes two branches CD and EF connected in parallel.
- the branch CD includes two diodes 13 and 15 in opposition and directed in the non-conducting direction for the incoming current I.
- the branch EF includes two thyristors in opposition and directed in the conducting direction for the incoming current I.
- the two branches CD and EF are connected by an LC-type oscillating circuit comprising a capacitor 21 and a coil 23 which also serves as a repulsion coil for the repulsion disk (not shown) bearing the moving contacts bridge 7, 7'.
- the device is connected to a network such that the DC current flows from A to B and is equal to its nominal value when a fault occurs.
- a current ogive starts to form in the thyristor 17--capacitor 21--coil 23 circuit and is divided in the diode 13 (circuit HC) and in the circuit H-D-3-8 where it will be subtracted from the main current in order to rapidly bring it to zero. It is obvious that the growth of the current ogive is of an order of magnitude at least greater than that of the maximum fault current in order to produce a rapid cancellation of the current in the main contact 8.
- the contact 8 is open and continues its travel so that it can carry a significant voltage.
- the space between the terminals is not ionized and no wearing of the contacts is caused.
- the current in the diode 13 is equal to the difference between the external circuit current and the ogive current.
- the fault current continues to increase but it has been transferred from the contact 8 to the electronic assistance circuit.
- the upstream and downstream currents i.e. the current supplied by the source and the current in the fault are identical.
- the fault current will therefore decrease, due to the apparition of this antagonistic voltage.
- the assistance circuit according to the present invention is substantially symmetrical, a similar reasoning can be developed when the current is flowing from B to A.
- FIG. 3 shows an advantageous embodiment of the circuit of FIG. 1 in which there has been added a free-wheeling diode 24 and a non-linear resistor 25.
- a dissociation of the functioning of the upstream and downstream circuits takes place.
- the inductance of the circuit downstream of the contact breaker biases the diodes 24 and 15 in the forward direction and it can free-wheel until it damps out with a time constant associated with the said circuit.
- the current in the circuit upstream of the contact breaker reduces as the voltage at the terminals of the capacitor 21 increases.
- a non-linear resistor 25 has been provided in order to dissipate this energy and to thus clip any excess voltage greater than the stated values.
- the said non-linear resistor 25 can also be connected in parallel with the capacitor 21. In this case, it is however continually subjected to a voltage, which can effect its lifetime.
- the electronics triggers a thyristor, namely the thyristor which closes the oscillating circuit and which is directed in the conducting direction for the main current. It is however also possible to command the two thyristors 17 and 19 simultaneously. In this case, however, it is necessary to give a different rating to the capacitor since the ogive, in this case divided by two, must always be capable of exceeding the rise in the fault current.
- the contact breaker starts to act against the short circuit at the instant t 4 , i.e. less than one millisecond after the current reaches its triggering value.
- the maximum value reached by the fault current is therefore of the same order of magnitude as the triggering current even in the case of very serious short-circuits.
- the maximum value reached by the current and the speed of the cut-off are such that the I 2 t in the case of a serious short-circuit is several orders of magnitude lower than the value relating to conventional devices.
- the contact breaker according to the invention can cut off any current according to the same principle. It is characterized therefore by the absence of a critical current.
- contact breaker described above can also be used to cut off a nominal current while being remotely controlled, manually for example, instead of by a fault current reaching a triggering threshold.
- the contact breaker according to the present invention is particularly suitable as a current limiter in medium voltage applications and although more particularly suited to DC electric traction in rolling stock or in fixed equipment, it can also be used in AC applications.
- the means enabling galvanic isolation advantageously connected in the branches 1-C and possibly 3-D or H-24 (see FIG. 3) consisting of suitable switches 33 and 35, can be used to carry out line tests either to check the state of the line using a small current before it is engaged, or for checking the state of the insulators for example.
- a control known in itself, of one at least of the said switches, which enables opening and closing according to a cycle at a relatively low frequency in the order of 0.1 Hz, for the purpose of being able to work with a larger current, in the order of 5 A for example, without damaging the assistance circuit while allowing a good visual assessment of the insulators.
